Embodiment Construction
[0046]In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0047] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is considered to be "coupled" to another element, it indicates that the change of at least one...

The invention provides a surgical instrument, a slave operation device using the surgical instrument and a surgical robot having the slave operation device. The surgical instrument comprises an end effector, a driving device and cables, the driving device is configured to drive the end effector to move through the cables, the driving device is configured to drive the slave operation device to move, the cables comprise a first pair of cables and a second pair of cables used for driving the end effector to execute yawing motion, and a third pair of cables used for driving the end effector to execute pitching motion, and the yaw motion of the end effector is orthogonal to the pitching motion, so that a coupling relationship exists between the third pair of cables on the end actuator and the first pair of cables and the second pair of cables. The driving device is provided with a decoupling mechanism for decoupling the coupling relationship, the decoupling mechanism comprises a main decoupling piece and an auxiliary decoupling piece, the main decoupling piece is in a cam shape, the main decoupling piece and a third driving unit rotate coaxially, and the main decoupling piece and the cam structure drive the auxiliary decoupling piece to slide so as to release the coupling relation.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a surgical instrument, a slave operating device using the surgical instrument, and a surgical robot with the slave operating device. Background technique [0002] Minimally invasive surgery refers to a surgical method that uses modern medical instruments such as laparoscopy and thoracoscopy and related equipment to perform surgery inside the human cavity. Compared with traditional surgical methods, minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. [0003] With the advancement of science and technology, robotic technology for minimally invasive surgery has gradually matured and been widely used. A minimally invasive surgical robot usually includes a main operation console and a slave operation device. The master operation console is used to send control commands to the slave operation device according to the doctor's operation to con...
